Title: Improvements in or relating to the sizing of dyed yarns
IPC: D06M15/15
Filed: 1929-07-13
Abstract: 315,428. British Celanese, Ltd., (Assignees of Platt, H.). July 13, 1928, [Convention date]. Yarns, treating with Liquids.-The tendency to bleed in the sizing and subsequent de-sizing of dyed yarns is reduced by using as size a composition which contains glue or gelatine and which is substantially neutral. The process is more particularly applicable to yarn made of or containing organic derivatives of cellulose such as cellulose acetate which has been dyed with certain water insoluble dyes that are solubilized by means of a dispersing agent. As suitable dyes are mentioned anthraquinone vat dyes such as 1.4 dimethyldiamino anthraquinone or 2.4 dinitro-4'- amino-diphenylamine, or " Setacyl," or the so called direct or " Dispersol " dyes. The sizing bath may be composed of gelatine 9 lbs., glycerine 2 lbs., castor oil 1.5 lbs., sodium benzoate 0.25 ozs., water 260 lbs., and is given a pH value of 7 to 7.5 by the addition of sodium carbonate. It is used at a temperature of 70 C. After the yarn has been sized it is woven or knitted into a fabric or otherwise worked and then de-sized by treatment with water at 50-70 C.

Abstract: 837,077. Knot-tying devices. ZELLWEGER Ltd. July 7, 1958 [July 6, 1957], No. 21694/58. Class 112 In a knot-tying device comprising a sleeve about which loops are formed, and a hook longitudinally displaceable into the sleeve to draw the threads therein during completion of the knot, a threadclamp which holds the thread ends while the loops are being formed is positively opened when the thread-ends are engaged thereby and also when the hook moves into the sleeve. As shown, a hook 2 is longitudinally displaceable into a stationary sleeve 1 on which is journalled a hollow shaft 4 adapted to rotate 3 times for each knot-tying operation. A sleeve 6, which is slidably coupled to shaft 4 by means of a key 3, is formed with a gear 5 and a radial flange 7 spaced from the latter. A forked member 9 disposed between gear 5 and flange 7 is displaceable by means of a shaft 10 for shifting' sleeve 6 axially on shaft 4. A gear 13, journalled on sleeve 6, has an extended hub 14 which abuts a collar 16 fixed to sleeve 6 by a grub screw 15. Gears 5, 13 are interconnected by gears 10, 12 journalled in fork 9, the arrangement being such that gear 13 rotates in the same direction as gear 5 but only once for each knot-tying operation. A sleeve 17 carried by collar 16 is rigid with a fixed thread-clamping jaw 18 and contains a plunger 20, one end of which carries a movable thread-clamping jaw 19 and the other end of which is biased by a spring 22 into engagement with a side face of gear 13. Said face is formed with a cam 23 which subtends an angle of 40 degrees and which is adapted to engage plunger 20 for opening jaw 19. The arrangement is such that jaw 19 remains open from 30 to 90 degrees during the first revolution of gear 5 when the thread ends are engaged by the jaws, and also remains open from 210 to 270 degrees during the second revolution of gear 5 when hook 2 draws the threads tied therein into the interior of sleeve 1. It is stated that the arrangement enables spring 22 to be made sufficiently strong to prevent the inadvertent slipping of elastic cords from between the jaws 18, 19. The jaws may also be roughened to enhance their grip.

Abstract: 300,945. Carter, E. B. Aug. 19, 1927. Feeding articles from hoppers and shoots.- Apparatus for feeding articles such as washers to the pins of rubber-heel moulds &c., comprises a carrier for supporting a column of the articles, and means which are operated by the pins for detaching the bottom article of the column. In the application to the placing of washers on the pins 6, Figs. 1 and 8, of a heel mould, the carrier 2, is provided with a number of columns 7 each of which distributes the washers to the pins in one row as the carrier is moved across the mould. Each column 7 is supported at its lower end in a member 32 which is mounted by a spring arm 30, allowing vertical displacement, on the carrier 2, and is provided with guide plates 48 to maintain it in alignment with the row of pins. Mounted in the member 32 is a sliding plate 44, actuated by a bell-crank lever 41, and a fixed abutment 40 so as to feed forward one of the washers when the member 32 is lifted by contact with a pin 6. The bottom plate 45 of the. member 32 is slotted at 49 to allow the point of the pin to enter the hole in the washer and remove it from the column. In the construction shown, the column of washers is threaded on a wire 11 which is secured at its upper end by a slot 18, Fig. 5, and spring catch 23 in the top plate 14 of the carrier. Alternatively, tubes may be used in place of wires for carrying the reserve washers.

Abstract: 784,805. Magnetically steered toy vehicles. FAVRE, R. July 29, 1955 [July 29, 1954; Jan. 14, 1955], No. 22077/55. Class 132(3) A toy vehicle is steered by the interaction of a magnetic track or tracks with a magnet carried by the vehicle. In Figs. 2, 3, 4 a magnet A is attached to a bracket E carrying rollers g<SP>1</SP>, g<SP>2</SP>, the magnet and bracket both being pivoted on a shaft O. A disc D, engageable by one or other of the rollers g<SP>1</SP>, g<SP>2</SP>, controls the steering by means of a pinion I and a rack J, and is normally retained in its central position by a torsion wire F; the rollers are rotated in the direction shown by shafts T1, T2 driven by the vehicle driving means M. When the vehicle deviates from the line of the tracks P1, P2, the magnet is caused to rotate in a direction depending whether the vehicle is moving to the right or to the left, and the appropriate roller g<SP>1</SP> or g<SP>2</SP> engages and rotates the disc D thus causing the steering to be corrected. In a construction for use with a single magnetic track, Figs. 6, 7, a bar magnet C is supported in a box-like part H and has pole pieces M<SP>1</SP>, M<SP>2</SP> secured by L-shaped pole members D<SP>1</SP>, D<SP>2</SP> and a non-magnetic member E. A non-magnetic axle B is attached to the part H which is pivoted at P<SP>1</SP>, the shaft 0 enabling the magnet asssembly to pivot from the normal position shown. When the magnet is inclined from the horizontal, one or other of the members D<SP>1</SP> D<SP>2</SP> engages. a wheel on the axle B which is thus rotated on its vertical pivot and the steering corrected; a spring R normally causes the vehicle to steer straight ahead. A track fork-member Fig. 12, has an electromagnet F" for controlling the direction of a vehicle on to one or other of the forks of the track P. The steering mechanism may be controlled by means of an electromagnetic device whose excitation current is controlled by the steering magnet. The rear face of the vehicle may be provided with a magnet for interaction with the magnetic track thus preventing skidding of the vehicle. To improve the interaction of the magnetic track and the steering magnet, the edges of the track may be notched.

Title: Process for the manufacture of primary phosphines
IPC: C07F9/50
Filed: 1960-06-23
Abstract: Primary alkyl-, aralkyl- and cycloalkylphosphines and alkylene diprimary phosphines are prepared by reacting exothermically in an inert gaseous atmosphere a melt of a complex compound of general formula AlX3.PH3, where AlX3 is an aluminium halide acting as a Lewis acid, with appropriate mono- or dihalogenated hydrocarbons in which the halogen is bound to an aliphatic or cycloaliphatic carbon atom. Preferably the halocarbon is added to the melt at a rate such that the heat of reaction maintains the liquid phase, and the primary phosphine is recovered from the reaction products after hydrolytic decomposition.  Reaction temperatures of 80 DEG -130 DEG C. are mentioned but the reaction may be continued at 50 DEG -60 DEG C. once it has started.  Solvents may be present.  Examples describe the preparation of n-alkyl phosphines containing 4, 5, 6, 8, 9, 10, 12, 14, 16 and 18 carbon atoms, of t-butyl, cyclopentyl and cyclohexyl phosphines and of 1,10-decamethylene diphosphine.  Some di-n-butyl phosphine is obtained in Example 1.
